General information:
On 1B 30 / 40 engines from the start of series production,
an injector with oil leak-off return line to the tank was intro-
duced.
Retrofitting:
– Remove the edge at the angle for fuel tank 1 as illus-
trated.
– Drill an 8.3 - 8.5 mm diameter hole in the tank at the
point shown, and deburr it.
– Insert the rubber grommet and hose nipple.
NOTE: Only the new injector is available as a spare part. All
the parts needed for retrofitting are supplied with it.
Fuel return line:
From the end of 1998 on, the fuel return line was modified
again.It now consists of fuel line 2, restrictor 3, fuel pipe 4,
coil spring 5 and fuel lines 6.The complete line 7 is sup-
plied as a spare part.
NOTE: The lines for 1B 30 and 1B 40 engines are of differ-
ent lengths.
Assembly instructions:
– Install return pipe 4 so that the end of the pipe in the
tank faces towards the outlet nipple.
